ADJUSTABLE WIND-GAGE REAR SIGHT FOR SMALL-ARMS.

To all whom it may concern:

Be it known that I, WINCHESTER BEN- NETT, a citizen of the UnitedStates, residing at New Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in AdjustableWind-Gage Rear Sights for Small-Arms and I do hereby declare thefollowing, when taken in connection with the accompanying drawings andthe characters of reference marked thereon, to be a full, clear, andexact description of the same, and which said drawings constitute partof this specification, and represent, in

Figure 1 a view in front elevation of an adjustable wind-gage rear sightconstructed in accordance with my invention. Fig. 2 a broken viewthereof in rear elevation, showing the central portion of the device.Fig. 3 a broken view thereof in vertical cen tral section on the line abof Fig. 1 and also showing the central portion of the device. Fig. 4 adetached view in rear elevation showing the circular operating-plate,the wind-gage slide and the disk or eyepiece combined as in use. Fig. 5a detached view of the circular operating-plate. Fig. 6 a correspondingview of the wind-gage slide. Fig. 7 a corresponding view of the disk oreygipiece.

1 y invention relates to an improvement in adjustable wind-gage rearsights for small arms, the object being to produce a simple, compact,effective and convenient sight con structed with particular reference tofew'ness of arts and reliability in use.

ith these ends in view my invention consists in an adjustable wind-gagerear sight having certain details of construction and combinations ofarts as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I form a rectangular,horizontally arranged opening 2 in the center of a disksha ed eye-piece3 having its rear face slightly concaved, and its forward face formedwith a horizontally arranged, undercut diametric slot 4 for thereception of a long narrow wind-gage slide '5 which has its edgesbeveled to fit into the said slot 4, and which is formed midway of itslength with a peep or sight-hole 6, and provided at one enc with anoperating pin 7 entering a camslot 8 in a circular operating-plate orwheel 9 having a knurled edge and adapted in di- Specification ofLetters Patent.

Serial No. 469,607.

ameter to project a trifle beyond the edge of the eye-piece 3 againstthe flat forward face of which it bears whereby the said plate may begrasped by its edges from the rear of the device, and so operated withthe utmost convenience by the user of the arm. The said eye-piece 3 isformed upon its forward face with a forwardly projecting, exterior-1ythreaded shank 10 having a wide slot 11 located in line with the slot 4and providing for the reception of the wind-gage slide 5. The plate orwheel 9 is formed with a central openlng 12 receiving the said shank 10on which it rotates as upon a center. It will be understood that byrotating the plate 9 in either direction, the slide 5 will be movedhorizontally to the right or the left as may be required for shiftingthe sight-h0le 6 to one side or the other of the vertical center of thesight to compensate for the velocity of the wind. In shifting the slide5 in either direction the user of the sight is guided by a graduatedscale 13 upon the lower edge of the opening 2 in the eyeiece 3. Byconcaving the rear face of t e eyepiece, disturbing side rays of lightare shut out, whereby C{the graduated scale is made easier to rea Asherein shown the eye-piece 3, slide 5, and operating-plate 9 are mountedupon what is called, a rear-sight leaf 14 having a slide 15 throughwhich the shank 10 of the eye-piece passes, the projecting rear end ofthe said shank receiving a nut 16 by means of which the eye-piece andits related parts are held in place. The said slide 15 is verticallyadjusted by a traverse screw 17 mounted in the leaf 14 and provided atits upper end with a knurled operating button 18. The lower end of theleaf 14 is provided with a knuckle 19 adapting it to be pivotallyconnected with an ordinary sight-base which is not shown. The said leaf14 forms a carrier, as it were, for the eye-piece 3 and the severalparts combined therewith.

I claim:

1. In an adjustable wind-gage rear sight for small arms, the combinationwith an eyepiece having its rear face concaved and formed with acentrally arranged oblong opening having one of its horizontal edgesprovided with a graduated scale, of a windgage slide located in front ofthe said eyepiece and formed with a sight hole-which is exposed throughthe said opening there in the eye-piece, and means for adjusting thesaid slide and holding it in any position of adjustment.

2. In an adjustable wind-gage rear sight for small arms, the combinationwith a diskshaped eye-piece-havin its rear face concaved, provided inits orward face with a longitudinal slot and formed with a horizontalopening coincident with the said slot and having one of its ed esprovided with a graduated scale; of a side located in the said slot andformed with a sight-hole which is exposed through the said 0 ening, andmeans for operating the said side to shift the position of thesight-hole.

3. In an adjustable wind-gage rear sight for small arms, the combinationwith an eye-piece having its rear face concaved and formed with acentral opening, of a longitudinally movable wind-gage slide located infront of the said eye-piece and formed with a sight-hole which isexposed through the said opening therein, and an annular operating platebearing upon the front face of the eye-piece than which it is a triflelarger in diameter and connected with the slide for the operationthereof, whereby the operating-plate may be grasped by its edges fromthe rear of the device for its operation.

4. In an adjustable wind-gage rear sight, for small arms, thecombination with a disk shaped eye-piece having its front face concavedand formed with a central longitudinal opening and provided in its rearface with a diametric slot located in line with the said opening, of amovable wind-gage slide annular operating-plate formed with a cam-' slotreceiving the said pin for the operation of the slide.

6. In an adjustable wind-gage rear sight, the combination with adisk-shaped eyepiece having a central opening and a for-' wardlyprojecting threaded shank, of a windgage slide mounted in the eye-pieceand passing through the said shank, an annular operating plate connectedwith the slide for operating the same and turning upon the said shank asupon a, center, a carrier receiving the shank, and a nut applied to theshank for securing it to the carrier.

7. In an adjustable wind-gage rear sight, the combination with acarrier, of a vertically movable, disk-shaped eye-piece mounted upon thesaid carrier and formed with a central opening, and also with a slot, ofa windgage slide located in the said slot, a circular operating plate orwheel having bearing against the forward face of the said eyepiece andconnected with the said slide for operating the same, a forwardlyprojecting shank passing through the said plate and carrier, and a nutapplied to the projecting end of the shank.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
